Within two hours driving from Húsavik, there are plenty more or less easy to reach places of interest. One of them is the Goðafoss waterfall, which is visible right from the ring road. Nearby, but not quite so easy to reach is the Aldeyjarfoss.
To get there, one follows 842 south (a dirt road, better than 844, which is an alternative). This turns after a few bumpy kilometers into F26. Most people drive their two wheel drive cars up to the parking lot.
The waterfall itself is quite impressive, but its real beauty is due to the large basalt formations surrounding it.
Next to it are some more contemplative smaller falls,
and a short hike takes you to another large fall, the Hrafnabjargafoss.
On the way, the rock formations on the river banks have the appearance of ancient friezes, telling stories about civilizations long forgotten.
The complexity of this place made of rock and water is quite overwhelming.
